Filed: 1998-05-12
Granted: 2001-05-20
Abstract: FIELD: production of commercial acetone with high resistance to oxidation. SUBSTANCE: commercial acetone is produced by its separation from products of decomposition of cumene hydroperoxide by multistep rectification. Separated as overhead product in the first column is acetone flow and obtained in still is phenol flow. Acetone flow is directed to partial condenser in which weight ratio of vapor and condensed flows ranges from 1:0.02 to 1: 0.1. Condensed phase is directed to fraction distillation reflux of the first column. Noncondensed products are directed to the second column of separation by rectification to which supplied simultaneously above feed tray is aqueous solution of sodium hydroxide in terms of 100% NaOH from 0.0036 to 0.006 t per one ton of acetone depending on required value of permanganate test from 10 to 70 h. Drawn as everhead product in the second column is aldehyde fraction directed to neutralization stage and flow containing acetone and water is withdrawn as side-cut distilled in vapor phase and directed to partial condenser to separate into liquid and vapor phase with weight ratio of phases from 1:10 to 1:100, respectively. Vapor phase of partial condenser is directed to the third column where commercial acetone is drawn off as overhead product. Still product of the third column presenting acetone aqueous solution is returned to the second column. Liquid phase of partial condenser is treated with solution of alkali and returned, either, to the second, or to stage of neutralization of products of decomposition of cumene hydroperoxide. The second version of method embodiment provides for one column for separation of commercial acetone from vapor phase of partial condenser after the first rectification column. In this case, acetone is drawn off as column overhead product and directed to partial condenser for production in it of liquid and vapor phases in ratio from 1:50 to 1:150, respectively. Vapor phase is condensed in cooler with obtaining of commercial acetone, and liquid phase is treated with aqueous alkali solution and subsequent return of produced raw acetone to the second column, or to point of feed or reflux. EFFECT: production of commercial acetone with high resistance to oxidation. 2 cl, 2 dwg, 1 tbl, 5 ex

Granted: 2002-05-20
Abstract: FIELD: water transport; designing floating structures provided with units for dampening waves. SUBSTANCE: device is designed for dampening vertical component of motion of floating structure caused by waves; it is provided with skirt projecting downward under bottom portion of structure; it consists of several passages which run horizontally and meet together from inlet hole to outlet away from floating structure. When structure moves down, water is forced to pass through passages from below forming jet effect which acts together with dampening effect on vertical motion of structure. Skirt of dampening unit may project outside on floating structure. Some first holes pass in vertical direction; they are connected with second holes which mainly pass in horizontal direction. Thus, they force water to change vertical direction of motion relative to floating structure through first holes mainly to horizontal direction of motion through second holes for passage of water through damper. EFFECT: enhanced operational efficiency of dampening at retained small dimensions. 16 cl, 10 dwg

Abstract: FIELD: electronic engineering. SUBSTANCE: magnetron anode block has T-shaped anode sections provided with radially extending part and circumferentially extending one; cylindrical surfaces of circumferentially extended parts in assembled magnetron are facing cathode. Using T-shaped sections makes it possible to enhance inductance and, hence, to generate low-frequency radiation without increasing magnetron size compared with prior art. In order to additionally reduce frequency capacitance is raised by using more than two anode bundles, and better four ones, at each end of anode block. Best way is building anode block in magnetron using high-strength magnetic field of about 500 Gs and operating at frequency of 100 MHz. Anode package as such may be component part of closing loop of magnetic-field liners of force. EFFECT: ability of operating at low frequencies; reduced mass and space requirement. 34 cl, 5 dwg

Abstract: FIELD: mechanical engineering; fuel equipment of internal combustion engines. SUBSTANCE: invention is aimed at prevention of undesirable too long delivery of fuel for injection at malfunctioning of nozzle in operation which precludes breakage of engine caused by overfuelling. Internal combustion engine with valve-type nozzle is furnished with high-pressure fuel accumulator into which fuel is fed by high-pressure pump and which is connected by pressure line with pressure space of valve-type nozzle provided with needle. In direction of opening, needle is loaded by pressure prevailing in pressure space acting onto conical surface against closing force, and in direction of closing it is loaded at least mediately by pressure prevailing in distributing space and acting onto movable wall connected with needle of valve-type nozzle and limiting said distributing space. Force created by first pressure prevailing in distributing space builds up closing force which exceeds force acting onto conical surface in direction of opening of valve-type nozzle needle, also provided with distributing valve operated by electric drive. Valve opens drain channel connecting distributing space with relief space to decrease pressure prevailing in distributing space to value of second pressure at which closing force is built whose value is less than force acting in direction of opening. Safety valve is installed in pressure line by means of which high- pressure fuel accumulator is connected with pressure space at the moments which fuel injection should take place and is closed during separate phases of injection. Distributing space is connected with high-pressure fuel accumulator through first restrictor. Distributing valve with electric drive is made in form of 2/2 distributor. Said distributing space can be connected with relief space second restrictor whose passage section exceeds passage section of first restrictor. EFFECT: improved reliability of fuel injection. 21 cl, 10 dwg
